Extract from STI description:

"EJ20 Boxer engine, cogged timing belt which was adapted with strengthened rubber. In difficult morosport use, this specification was used to avoid tooth jumping and to resist higher temperatures. We have been using this on the WRC car since."

As with ALL of our products, this is a GENUINE STI PRODUCT which we buy direct from Japan.
